Filter by:Patients hospitalized in intensive care between January 2014 and September 2021 for ketoacidosis complicated by organ failure in participating departments.
The investigators propose a multicenter prospective study in patients undergoing either an elective bariatric procedure or an elective benign procedure, including laparoscopic/open cholecystectomy, laparoscopic/open hiatus hernia repair, laparoscopic/open inguinal hernia repair, laparoscopic/open umbilical hernia repair or laparoscopic ventral wall hernia repair. Perioperative blood ketone and venous blood gas levels will be measured pre-surgery, post-surgery and on post-operative days until discharge. Our primary research objective is to clarify the expected perioperative ketone and blood gas levels in elective bariatric patients who have been on a VLCD and fasting for surgery, compared to elective surgical patients who have only been fasting prior to surgery.
Hypothesis 1. To define whether stimulation of ATGL and suppression of G0/G1 switch gene occur in the initial phases of diabetic ketoacidosis and thus can be identified as the primary mechanisms behind this life threatening condition. 2. Make a human model for studying ketoacidosis. The investigators plan to reduce in their regular insulin over night. In the morning we administer endotoxin, which together with a relative lack of insulin will initiate ketogenesis - a state of ketoacidosis. On another occasion strict glycemic control is imposed by means of intravenous insulin. The testing is done two separate days with at least 3 weeks in between and patients are admitted to hospital the evening before the day of testing. The investigators use isotopic tracers to determine metabolic fluxes and analyse fat (ATGL, G0/G1 switch gene) and muscle biopsies.
Diabetes mellitus type I (DM I) is characterized by lack of endogenous insulin and these patients are 100% dependent on insulin substitution to survive. Insulin is a potent anabolic hormone with its primary targets in the liver, the skeletal muscle-tissue and - adipose-tissue. Severe lack of insulin leads to elevated blood glucose levels, dehydration, electrolyte derangement, ketosis and thus eventually ketoacidosis. Insulin signalling pathways are well-known. Growth hormone (GH) is also a potent anabolic hormone, responsible for human growth and preservation of protein during fasting. GH (in concert with lack of insulin) induces lipolysis during fasting. It is not known how GH exerts its lipolytic actions. The aim is to define insulin and growth hormone (GH) signalling pathways in 3 different states in patients with DM I. And to test whether ATGL-related lipolysis in adipose tissue contributes to the development of ketosis. 1. Good glycemic control 2. Lack of insulin (ketosis/ketoacidosis) 3. Good glycemic control and GH injection
This is a randomized controlled trial comparing the time needed to get the conditions to space hourly controls to controls every 4 hours, using the one bag system versus the two bags system, in the initial treatment of children with diabetic ketoacidosis. After fast infusion of isotonic saline solution (20 ml/kg) to prevent shock, the administration of maintenance fluids and insulin therapy is indicated. Hourly plasmatic levels of glucose controls could determine changes in glucose IV administration. On using the classic one bag system each change determine a bag change. Using the two bag system allows to deliver the patient the appropriate glucose infusion in less time.
